BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for molding a corrugated tube,

본 발명은 지중에 매설되는 하수암거의 내부에 설치되어 오수를 우수와 분리시켜 이송시키는 우오수관과 같은 관체 성형장치에 관한 것이다.The present invention relates to a tube forming apparatus, such as a sewer pipe, installed inside a sewage cage buried in the ground,

이를 상세히 설명하면, 압출기에 의해 용융된 열가역성수지조성물(버진재료:패릿)의 레진으로 우오수관과 같은 관체(다각형관 또는 원통관)를 연속적으로 압출 성형하고, 연속적으로 압출 성형되어 배출되는 관체의 형상ㆍ모양이 변형되지 않도록 유지시키면서 냉각시켜 형성하며, 형상ㆍ모양이 유지되는 관체(다각형관 또는 원통관)를 괘도형으로 작동되는 인취장치에 의해 인취하면서 컷팅장치에 의해 일정한 길이로 컷팅하여 배출시키도록 하는 관체 성형장치를 제공하려는 것이다. In detail, a tube (polygonal tube or circular tube) such as a water pipe is continuously extruded by a resin of a thermally reversible resin composition (virgin material: parit) melted by an extruder, (A polygonal tube or a circular tube) whose shape and shape are maintained is cut by a cutting device to a certain length while being taken by a drawing device operated in a trapezoidal manner And to discharge the tubular molding device.

본 발명에 의해 제조되는 우오수관과 같은 관체와 유사한 것으로는 국내의 특허등록 제10-733608호의 '하수암거 부착식 우오수분리장치'에 '오수분리관'이 개시되어 있으며, 이를 첨부된 도면 도 1을 참조하여 설명한다.A sewage separation pipe is disclosed in Korean Patent Registration No. 10-733608, which is similar to a pipe for a sewage pipe manufactured by the present invention, 1 will be described.

오수분리관(1)은 밑면(2)의 양단에는 상대적으로 길이가 길고 짧은 장수직 면(3)과 단수직면(5)이 나란하게 형성되어 있고, 장수직면(3)의 상단에는 상면(4)이 밑면(2)과 나란하게 형성되어 있으며, 상면(4)의 선단과 단수직면(5)의 상단은 경사면(6)에 의해 일체로 연결되어 있다.The sewage separating pipe 1 is formed at both ends of the bottom surface 2 with a relatively long length and a long long vertical surface 3 and a single short side surface 5 in parallel. And the upper end of the upper face 4 and the upper end of the lower face 5 are integrally connected to each other by the inclined face 6.

상기와 같이 형성되는 오수분리관과 같은 다각형 관체를 성형하는 장치로서는, 국내의 공고실용신안 공고번호 제20-1986-395호(흡입냉각 합성수지관 성형기)와 공고실용신안 공고번호 제20-1997-4852호(압출성형기의 진공식 냉각장치) 및 특허 등록 제10-361937호(소형4각관의 성형장치)가 알려져 있다.As a device for molding a polygonal tubular body such as the sewage separating tube formed as described above, there have been proposed a molding method for molding a polygonal tubular body such as a sewage separating tube, such as a domestic public utility model No. 20-1986-395 (inhalation cooling synthetic tube molding machine) and a public utility model No. 20-1997- No. 4852 (patent pending cooling device of extrusion molding machine) and patent registration No. 10-361937 (molding device of small square pipe) are known.

공고실용신안 공고번호 제20-1986-395호(흡입냉각 합성수지관 성형기)에 예시된 관체성형장치는, 관압출기의 배출구 측에 흡입냉각 합성수지관 성형기를 구비하여, 관압출기에서 성형되어 배출되는 관체를 미세공이 조밀하게 뚫어진 흡입냉각 합성수지관 성형기의 실린더(유통관)로 통과시키면서 미세공을 통해 실린더(유통관)의 내부공기를 흡입하여 성형되어 이송되는 관체의 형상을 유지하고, 실린더(유통관)의 외측에 형성된 냉각실에서 냉각수를 순환시켜 실린더(유통관)의 내부를 통과하는 관체를 냉각시키도록 된 것이다.The tubular molding apparatus exemplified in Published Utility Model Publication No. 20-1986-395 (suction cooled synthetic resin tube molding machine) is provided with a suction cooling synthetic resin tube molding machine on the discharge port side of the tube extruder, (Flow tube) of a cylinder (flow tube) through which fine holes are densely packed, sucking the air inside the cylinder (flow tube) through the fine holes to maintain the shape of the tube to be formed and transported, The cooling water is circulated in the cooling chamber formed in the cylinder (circulation pipe) to cool the pipe passing through the inside of the cylinder (flow pipe).

그러나, 이는 실린더의 내부공기를 조밀하게 뚫어진 미세공으로 흡입하므로 실린더의 내부를 통과하는 관체의 외면이 실린더의 내벽에 연접되면서 통과되도록 하므로 관체의 형상이 변형되는 것을 다소 방지할 수 있으나, 관압출기에 구비되는 성형다이(금구)의 구조가 단순하여 고도의 성형기능이 요구되는 다각형 관체를 효율적으로 성형시킬 수 없게 되고, 성형된 관체를 간접냉각방식에 의해 일 회만 실시하므로 냉각효과가 떨어져 두께가 두꺼운 관체의 생산에는 부적합하며, 성형 냉 각된 관체가 관압출기의 압력에 의해 배출되므로 생산성이 저하되는 문제가 있다.However, since the inner air of the cylinder is sucked into the fine holes drilled, the outer surface of the tube passing through the inside of the cylinder is inserted while being connected to the inner wall of the cylinder, so that the shape of the tube can be somewhat prevented from being deformed. It is impossible to efficiently mold a polygonal tube that requires a high degree of molding function because the structure of the molding die (metal) is simple, and the molded tube is subjected only once by the indirect cooling method, There is a problem that productivity is deteriorated because the tubes are not suitable for the production of tubes and the tubes that have been cooled are discharged by the pressure of the tube extruder.

공고실용신안 공고번호 제20-1997-4852호(압출성형기의 진공식 냉각장치)에 예시된 압출성형장치는, 성형다이가 장착된 압출기의 후측에 진공냉각장치와 인수장치를 차례로 구비하되, 진공냉각장치는 진공냉각조와 진공조를 상하로 연통되게 구비하여, 압출기에서 용융되어 배출되는 용융물(성형재료)이 성형다이를 통과하면서 성형품(관체)을 형성하고, 성형다이에서 성형 배출되는 성형품(관체)을 진공냉각수조로 통과시키면서 살수수단에 의해 살수되는 유체(냉각수)에 의해 냉각시키고, 진공냉각수조의 내부로 살수되는 냉각수를 하측의 진공조로 흡입 배출시켜 진공냉각수조를 진공상태로 유지시켜 주도록 된 것이다.The extrusion molding apparatus exemplified in Published Japanese Utility Model Publication No. 20-1997-4852 (a quasi-official cooling apparatus of an extrusion molding machine) is provided with a vacuum cooling apparatus and a taking-out apparatus in order on the rear side of an extruder equipped with a molding die, The cooling device is provided with a vacuum cooling tank and a vacuum tank so as to communicate with each other up and down so that the molten material (molding material) to be melted and discharged from the extruder passes through the molding die to form a molded product (tube) Is cooled by a fluid (cooling water) sprinkled by a sprinkling means while passing through a vacuum cooling water tank, and cooling water sprinkled inside the vacuum cooling water tank is sucked and discharged by a lower vacuum tank to maintain the vacuum cooling water tank in a vacuum state .

그러나, 이는 성형다이가 구비된 압출기에 의해 성형되는 성형품(관체)을 살수수단이 구비된 진공냉각조로 통과시켜 냉각시키고 냉각된 성형품(관체)을 인수(인취)장치에 의해 효율적으로 인수(인취)하므로 생산성을 다소 향상시킬 수 있으나, 성형다이(금구)의 구조가 단순하여 고도의 성형기능이 요구되는 다각형 관체를 효율적으로 성형시킬 수 없게 되고, 성형된 관체를 직냉방식에 의해 일 회만 실시하므로 냉각효과가 떨어지고 관체의 형상이 변형될 염려가 있으며, 진공냉각수조의 내부로 살수되는 냉각수를 하측의 진공조로 단순하게 흡입 배출시켜 진공냉각수조의 내부를 진공상태로 유지시켜 주므로 진공냉각수조의 내부에서 상하 및 전후의 진공도(압력)가 서로 다르게 되어 오히려 관체의 형상이 변형되는 염려를 배제할 수 없는 문제가 있다.However, this is because the molded product (tube body) formed by the extruder provided with the molding die is cooled by passing through a vacuum cooling bath provided with water sprinkling means, and the cooled molded product (tube body) However, since the structure of the molding die (metal) is simple, it is impossible to efficiently mold the polygonal tubular body that requires a high molding function, and the molded tubular body is subjected to only once by the direct cooling method, The cooling water flowing into the inside of the vacuum cooling water tank is simply sucked and discharged to the lower vacuum tank so that the inside of the vacuum cooling water tank is maintained in a vacuum state so that the inside and the outside of the vacuum cooling water tank There is a problem that the degree of vacuum (pressure) of the tube becomes different from each other, .

또 특허 등록 제10-361937호의 '소형4각관의 성형장치'는, 압출다이스가 구 비된 압출기의 배출측에 진공박스를 구비하되 진공박스의 선단에 냉각수단을 구비하여, 압출기에서 성형되어 공급되는 소형원형관을 진공박스의 선단에 냉각수단에 의해 냉각시켜 진공박스의 중앙선상에 형성된 4각형 사이징통로로 통과시켜 4각파이프로 성형하되, 사이징통로의 주변에 일정한 간격으로 조밀하게 흡입홀을 통해 4각형 사이징통로의 내부공기를 흡입하여 소형원형관이 4각형 사이징통로를 통과할 때에 4각파이프로 성형되도록 된 것이다. In addition, the 'small quadrangular tube forming apparatus' of Patent Registration No. 10-361937 has a vacuum box at the discharge side of an extruder having an extrusion die, and a cooling means at the tip of the vacuum box, The small circular tube is cooled by a cooling means at the tip of the vacuum box, and is passed through a quadrangular sizing passage formed on the center line of the vacuum box to form a quadrangular pipe, which is densely arranged around the sizing passage at a predetermined interval The inside air of the quadrangular sizing passage is sucked, and the small circular tube is formed into a quadrangular pipe when passing through the quadrangular sizing passage.

그러나' 이는 압출기에서 성형되는 소형원형관을 냉각수단에 의해 냉각시킨 후에 4각파이프로 성형시키므로 원형관을 4각파이프로 용이하게 성형시킬 수 없게 디고, 원형관을 4각파이프로 성형(변형)시키기 위해서는 사이징통로에 형성된 흡입홀을 통해 강한 흡입력으로 흡입하여야 하므로 성형이 더디게 진행되어 생산성이 떨어지며, 압출기의 배출측에 구비(장착)되는 압출다이스가 단순구조로 되어 있으므로 대구경파이프를 성형하기에는 적합하지 않은 폐단이 있다.However, since the small circular tube formed in the extruder is cooled by the cooling means and then formed into the square pipe, the circular tube can not be easily formed by the square pipe, and the circular tube is formed (deformed) Since the extrusion dies provided (mounted) on the discharge side of the extruder are of a simple structure, it is not suitable for molding the large diameter pipe There is a closed end.

본 발명은, 압출기에 의해 용융된 열가역성수지조성물(버진재료:패릿)의 레진으로 우오수관과 같은 관체(다각형관 또는 원통관)를 연속적으로 압출 성형하고, 연속적으로 압출 성형되어 배출되는 관체(다각형관 또는 원통관)의 형상ㆍ모양이 변형되지 않도록 유지시키면서 냉각시켜 형성하며, 형상ㆍ모양이 유지되는 관체(다각형관 또는 원통관)를 괘도형으로 작동되는 인취장치에 의해 인취하면서 컷팅장치 에 의해 일정한 길이로 컷팅하여 배출시키도록 하는 관체 성형장치를 제공하려는데 그 목적이 있다.The present invention relates to a method of continuously extruding a tube (a polygonal tube or a circular tube) such as a water pipe with a resin of a thermally reversible resin composition (virgin material: parit) melted by an extruder, (A polygonal tube or a circular tube) is held while being kept from being deformed, and the tube (polygonal tube or circular tube) in which the shape and shape are maintained is taken by a drawing device operated in a trajectory, To a predetermined length, and to discharge the tubular molding device.
